Re: [U-Boot] [PATCH v5 09/14] armv8: fsl-lsch3: Disable SMMU during Secure Boot

During secure boot, SMMU is enabled on POR by SP bootrom. SMMU needs to be put in Bypass mode in uboot to enable CAAM transcations to pass through.

During Nonsecure Boot, SP BootROM doesn't enable SMMU and at reset SMMU is in bypass mode.
